Description
Technical field
The present invention relates to a kind of continuous rigid frame PC track girders steel reinforcement cage binding clamping fixtures.
Background technology
Cross-saddle single-track traffic have low noise, climbing capacity is strong, turning radius is small, rapid and convenient, take up an area less, cost
The advantages that low, conducive to environmental protection.Its system is safe and reliable, is widely used in all over the world, at home the technology still in rise
Step section only carries out Pilot project construction operation in Chongqing City at present.
In the construction of straddle-type monorail, continuous rigid frame PC track girders make and precision controlling is the key that whole system skill
Art.This track girder has both guide function while doing load-carrying members, and alignment control precision prescribed is high, prefabricated completion
The track girder linear walking state for directly determining monorail train, can not expire by adjusting rail with reference to conventional track system
The linear requirement of foot.According to straddle-type monorail requirement, alignment control content includes mainly the lateral, vertical and axial of track girder
Deformation, the determination of beam length, and to fully consider that linear variation and concrete shrinkage and creep influence.Known PC track girders beam body
Steel reinforcement cage 13, as shown in Fig. 2, it has the elongated reinforcing bar 13-3 arranged along beam body length direction and is bound along beam body width direction
Rectangle hoop, rectangle hoop collectively forms by the stirrup side 13-2 of upper and lower stirrup bottom edge 13-1 and both sides again.
Track girder variable in length, and the segmental arc in beam-ends flat segments and beam between flat segments there are regular length, this is just
Cause that track girder bar types are more, the larger feature of weight, and since the construction of same traditional beam body is different, train can be straight
It is connected on track girder and travels.Therefore, reinforcing bar ties up safety and the smooth-going that the position that button is put directly affects train operation, this is just to beam
Body steel reinforcement cage binding precision has higher requirement.There is presently no dedicated lashing equipments to complete this work.
